Chapter 21: The Fundamental Theorem of Calculus in One Dimension



The act of integrating a function and that of differentiating one are inverse operations; thus the area under a curve is an antiderivative of its integrand as a function of the upper end of the area. We explore proof of this claim and its implications for one dimensional integrals.
